About onlinekeyboardtest.tech
Free, instant, and completely private keyboard diagnostic tools — built for gamers, typists, and hardware enthusiasts around the world.
Who We Are
onlinekeyboardtest.tech is an independent project built by a small team of keyboard enthusiasts who were tired of bloated, ad-heavy, or download-required keyboard testing tools. We believe that diagnosing a keyboard problem should take seconds — not minutes — and should never require installing anything on your system.
Our tools run entirely inside your web browser. There are no servers processing your keystrokes, no accounts to create, and no software to install. Whether you're on Windows, macOS, or Linux, everything works out of the box.
What We Do
We build and maintain a growing suite of free, browser-based keyboard diagnostic and testing tools. Every tool is designed to be fast, accurate, and easy to use — even for non-technical users.
Why We Built This
The idea started simply: we wanted a quick way to check whether every key on a keyboard was working after a coffee spill. Every tool we found either required a software download, sent keystroke data to remote servers, or was buried behind pop-up ads. So we built our own — and decided to make it free for everyone.
Since then, the project has grown into a full diagnostic suite covering mechanical keyboards, gaming keyboards with NKRO testing, laptop-specific layouts, input latency measurement, and more.
